I switched my ps3 from one tv to my vizio, and the voices of the characters arent being heard, but all of the background noise is. i have it hooked up with an hdmi cable, and the video is fine. i checked the menu and options and nothing seems to change this.

This is typical of sound systems that come with TVs, especially flat screens. You need to look into purchasing an external sound system, such as a sound bar or a surround sound system. That way you can have better control of background/voice ratios.

If it has a switch labeled conf/dict , put this switch in the dict mode. This switch is a record sensitivity control, in the conference position it will pick up almost any noise in the room. In the dict,position which is short for dictate, it will have less record sensitivity and will only pick up sounds very close to the microphone and eliminate background noises

I had this problem with my previous TV (Syntax by Olevia, an off brand). It only happened to me on certain channels, and for certain shows. What is happening is the TV station is broadcasting the audio in Dolby 5.1 format. For some stupid reason, the TV is playing the background speakers (effects) instead of the speaking parts. You get a little bleed-over of the voices into the back speakers, so voices are there but really quiet. Unfortunately my TV didn't have any surround sound options to fix this.

See if your TV has a surround sound option. Otherwise, you will need to connect the TV sound output to a surround sound system that can properly decode the audio channels.

Did you change TVs? I had that issue when I moved the PS3 into the bedroom which didn't have surround sound so I was only getting the front speakers. Reset your sound settings by automatic and it could well work again...

get your ps3 checked and are you sure you hooked up your audio and sound wire hooked up right and if that doesn't work than try using a HDMI cord it really helps............

Hi:
Check the video connector on the PS3 for a switch to switch from composit video to HD video.

Cell phones transmit the sound as digital data. The data when converted back to analog to listen too CAN have "digitizing noise" which will sound like static.

WORSENING the problem is if there is noise in the background of the person sending the voice and the worst possiblle is to have MUSIC in the background. These both drive the CODEC (the analog conversion system) crazy and will create what you describe. The CODEC is designed to transmit ONLY voice.

You are listening to a Dolby Digital source and you either don't have a center speaker hooked up or, it's not enabled. If you only have 2 speakers connected to a surround receiver, switch your receiver from surround to surround off. If this doesn't work, or you need more help, specify your system and how it's all hooked up.

What you need to do is hook up your PS3 to a different tv. Then in Display setting on the PS3 change it to 480p. Hook it up to your vizio and while on the ps3, change it back to 1080p. Most Vizios don't have a Progressive scan that adjusts to the output settings of the PS3 (or other device) .

i had the same problem with my acoustic solutions astv 3619ws, you have to change the settings to:

linear PCM 2 ch. 44.1 khz
linear PCM 2 ch. 48 khz
linear PCM 2 ch. 96 khz
linear PCM 2 ch. 192 khz

you have to unselect all the other settings.
